Adventures of Superman #427
Superman invades the country that sent a terrorist Voltron to Metropolis a couple of issues ago. The country is named Qurac, and is being lead by a certain president Marlo who’s-okay, screw this. The country is obviously modeled after Iraq and President Marlo looks like Saddam Hussein or one of his many body doubles. It was 1987.
So basically, Superman went to Qurac and used his super alien powers to throw tanks around whoop a few Quracis until he reaches the office of President Marlo and pushes him against a wall. Here comes the swerve: A couple of mysterious butt-ugly mutants living in Qurac’s sewers telepathically mess with Superman’s head, making him think he’s back on Krypton with his parents, who tell him he should be ruling the world. Superman has to abandon his meeting with the president and go for a nap in his hotel room (or Clark’s hotel room). Once there, the sewer mutants go back to messing with Superman’s head, making him see visions of past villains and potential lovers (Lois, Lana and Cat) taunting him about his motives for helping people. Superman resists, though, and the main mutant, Prana, dies from all the mental stress.
